Study of the effects of olive oil mill waste waters on the coastal ecosystem of Messiniakos Gulf
Summary:
In this thesis is presented for the first time an integrated study that tries
to link the physicochemical status of Messinian Rivers with the composition of
Olive Oil Mill Waste Waters (OMWW). In the prefecture of Messinia huge
quantities of OMWW are generated annually which are discharged into the
aquifer. The total pressures on the river system has been recorded from
industrial units (78% olive oil industries), land uses and rubbish dumps, the
composition of the waste was determined and a series of chemical analysis,
before, during and after of four production periods took place in small streams
that the waste is gathered, in the river water as well as in the estuaries of
the rivers in the Messinian Gulf. The samples derived from the five main rivers
that discharge into the Messinian Gulf (Pamisos, Aris, Velika, Epis and Nedon)
and their estuaries. The concentration of nutrients, heavy metals, with the
method of atomic absorbance, phenols with the chromatographic method of 4
amino-antipyrine and total organic carbon through catalytic oxidation were
recorded. Strongly increased concentrations of ammonia, manganese and phenols
were recorded in the water samples. An acute toxicity bioassay was performed in
the freshwater shrimp of Palaemonidea family and the lethal concentration 50
was recorded (0.7%, Very High Toxicity), also classification of the
physicochemical status of the stations based on nutrients took place according
to the Greek Classification System, (GR_NCS Skoulikidis 2006) where the station
before the estuaries of Pamisos river was classified as Poor (12/2010). The
chemical parameters were correlated with the pressures for each station using
principal component analysis and strong correlations resulted between phenols,
ammonia, Mn, Cu and Ni with the olive oil and wine industries.
